Measurement off three-phase electrical sizes on non-insusible form to microcomputer meter

In the paper is describing a procedure for measuring the three-phase electrical quantities used in power grids. Measuring the three-phase electrical quantities used in power grids was done with formulas that were implemented in the diagnostic block scheme using the Quartus II 13.0sp1 software package. A discrete (digital) algorithm was developed to obtain the effective values of voltage, current, active and reactive power. The results obtained are programmatically simulated, presented on the monitor or printed, and are applicable in practice.
